摘要
文章在建立动力总成悬置系统的动力学模型基础上,对应用停缸技术的某汽车动力总成进行刚体模态试验,并分析该停缸车动力总成的刚体模态结果。随后针对停缸车与普通车的动力总成刚体模态试验结果进行差异性研究,指出需要重点关注的模态阶次,对于停缸车动力总成悬置系统的设计开发具有一定的指导意义。
Based on the dynamic model of powertrain mount system,a cylinder deactivation vehicle powertrain rigid modal test is made,and the result is analyzed. A difference study is made between cylinder deactivation vehicle and normal vehicle,and the modal order that needs to be focused on is pointed out. It has certain significance for the design and development of powertrain mount system on the vehicle applying cylinder deactivation.
